The subject of this invention is a fuse forv projectiles The prlncipal object of the invention is to provide a coupling for holding a spring actuated plunger in position for assemblycoupling will also serve of the fuse which to restrain the plunger against rotary movement during functioning of the fuse.

WVith the foregoin and ther objects in view, my invention resides in the novel arrangement and combination of parts and in the details of construction hereinafter de-'.

scribed and claimed, it being understood that changes in the precise embodiment of the invention herein" disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

A practical embodiment of the invention is illustrated in the accompanying drawings,

wherein:

Fig. 1 is a longitudinal sectional view of a fuse constructed in accordance with the invention; i

Fig. 2 is a fragmentary sectional view through the plunger taken at right angles to Fig. 1;

Fig. 3 is asectional view on the line 33 of Fig. 1.

Referring to the drawings reference The invention is illustrated in connection with a combination instantaneous and deby numerals of lay action fuse of a type disclosed in Patent 5 is formed with a cavity 7 in its rear-portion in which is to be placed a plunger 8,

carrying an eccentrically disposed primer 9 which is to be set off by a stationary firing pin 10 fixed to the fuse head at the base of the cavity. r

The plunger is normally maintained in the unarmed position, by means of a pair springs 11 whichare seated against the floor of the cavity. WVhen the fuse body6 is attached to the fuse heada disk 12 inter posed between the two members forms a support to restrain movement of the plunger under the action'of its springs 11. Prior to assembling the fuse head and body the plunger is held against the action of the may be recessed as at 1 6lto receive thenut.

The belt 13 by being positionedeccentrioally of the plunger insures alinement of the primer 9 and firing pin 10 when inserting the plunger and prevents rotary movement of the plunger as it moves forward on impact.'

Movement of the plunger to the armed position during assembly of the vented by a c'entrifu'gally releasable locking pin 17 and also which is axially of-the fuse and is provided with'an enlarged movement of the plunger in the direction of'ar ming when the striker is held by means fuse is preby an impact striker 18.

portion 19 which limits of a removable cap 20. The striker is."-

adapted to functiona detonator 21 carried in a rotor 22 mounted in the fuse body 6.

I claim:

, V 1.. A fuse including a head, a body secured thereto, a plunger, an element of. a firing mechanism carried centrifugally by the plunger, a spring for maintaining the plunger in unarmed position, a bolt securable to the head and passing ec'centrically through the plunger and a nut on the end of the bolt for opposing the a-ction of the plunger spring.

2. In a fuse, a housing; a resiliently restrained plunger in the housing, and means passing eccentrically through. the plunger and secured to the housing for holding the plunger in position of assembly.

3. In a fuse housing, a resiliently restrained plunger in the housing and means passing through the plunger and secured in thehousing for holding the plunger in 7 position of assembly. I

4:- A fuse housing, a plunger within the housing, and means passing through the plunger and engaging the housing to hold the plunger assembled and guide the plunger in its reciprocato-ry movement. I

5. A fuse housing, a plunger within the housing; and means passing through the g plunger and engaging the housing to hold the plunger assembled.
